First of all, what’s a LINAC?
A linear accelerator (LINAC) is an x-ray or electron-based technology used in radiotherapy treatments1. Tumours are specifically targeted by a high dose of radiation to destroy cancer cells in a way that minimizes the damage done to normal surrounding tissue2.
However, with repeated use of the LINAC comes the production of radioactive impurities. Even after the LINAC has run its course, certain radioisotopes with longer half-lives (weeks, months and even years) are still present, and radioactive. Therefore, knowledge of isotope ID and the dose rate of the radioisotope mixture present is key for the dismantling process; ensuring contaminated parts are disposed of appropriately.
